WHlFFLETREE-CLIP.

SPECIFICATION forming part of Letters Patent No. 436,429, datedSeptember 16, 1890.

Application filed June 6, 1890. serial No. 354,439. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM M. MYERS, a citizen of the United States,residing at Cosby, in the county of Andrew and State of Missouri, haveinvented certain new and useful Improvements in Clips for Eveners, &c.,of

which the following is a specification, reference being had therein tothe accompanying drawings.

This invention is an improvement on the devices shown in Patent No.383,900, issued jointly to myself and Augustus Smith, June 5, 1888; andit consists in the peculiar construction and arrangement of partshereinafter particularly described, and then pointed out in the claims.I

In theaccompanyingdrawings,formingpart of this specification, Figure 1is a vertical cross-section on the line of the pivotal bolt at the endof the doubletree. Fig. 2 is a central longitudinal section through theend of the doubletree and the center of the singletree. Fig. 3 is areverse plan of the bearingplate attached to the singletree. Fig. 4 is aplan of the end of a doubletree, showing its bearingplate with its yokecut away. Fig. 5 is a plan of the central portion of the singletree andits clip.

Referring now to the details of the drawings by letter, A represents thedoubletree, of any suitable material or form, upon which is secured thelower or doubletree bearing-plate B, having (preferably formedtherewith) the clevis B, and provided with holes b, adapted to receiveordinary bolts 0, preferably having tapering square heads, which boltspass down each side of the doubletree and into a plate D below, similarto that in the aforesaid patent, where they receive nuts 0, and by thismeans the bearing-plate B and its clevis B are securely yet cheaply madeand secured in place.

Around the singletree E is secured a stirrup F, having threaded ends f,which pass through holes in the upper bearing-plate G, and are securedby nuts H, which stirrup and bearingplate are provided with holes toreceive the pivotal bolt 1, which also passes through the yoke B, thelower bearing-plate B, and the plate D, below which it receives a nut'5, whereby the whole is securely connected together. The top of thestirrup F is provided with ears f, having holes to receive ordinarybolts, which pass through them and through holes in corresponding earsg, formed on the upper bearing-plate G, which form additional means ofsecuring the parts together. The bearing-plate G has two annularprojections J K, leaving a groove between them, into which fits anannular projection M on the lower bearing-plate. The projection K fitsinto an aperture in the center of the projection M and receives the boltI. This arrangement of the projections will be found very efficacious inkeeping out grit from the bearing-plates, inasmuch as it will bepractically impossible for it to get at the central bearing of saidplates, even if it should reach the outer edges of the bearing betweenthe upper and lower bearing-plat es. It will be observed that thestirrup F with the nuts H I serve the double purpose of, first, firmlysecuring the upper bearing-plate in its position on the singletree, and,second, with said bearing-plate they form a perfect and secure bindingfor the singletree, effectually preventing the same from splitting.

From the above description and the drawings it will be seen that my newimprovement makes a connection between the doubletree and sin gletreesthat can be cheaply made, readily put together, durable in wear, andtherefore not likely to get out of order.

It is evident thatthese devices may be used for securing a whiffletreeto the crossbar be tween shafts where a doubletree is not used, and Ishould consider in such cases such cross-bar as the equivalent of thedoubletree shown in the drawings.

What I claim as new E 1. The combination, with a whiifietree and itspivotal bolt, of a stirrup F, having a central bolt-hole, and its endsthreaded and provided with nuts, an upper bearing-plate G, having holesto receive the ends of the stirrup, a central hole to receive thepivotal bolt, a groove on its under side, a lower bearing-plate securedto a suitable support and having an upward projection fitting in thegroove of the upper plate, and a pivotal bolt passing through thestirrup and the plates, substantially as described.

2. The combination, With a Whiffietree and its pivotal bolt, of theolevis B and plate B, permanently connected together and set on asuitable support, the independent bolts 0, having heads fitting in saidplate B, the plate D, having holes to receive the bolts 0 and thepivotal bolt, and the upper bearing-plate G, fitted to the plate B,substantiallyas described.

3. The combination, with a (loubletree and singletree, of the horizontalplate 13, having olevis B formed therewith, the plate G, fitting saidplate B, the stirrup F, fitted to the singletree and the plate G, theplate D beneath the doubletree, the bolts 0, passing through the platesB and D, and the pivotal bolt I,

passing through all the plates and the olevis, substantially asdescribed.

at. The plate and olevis B B, formed in one piece and provided withholes to receive the fastening-bolts C O I, in combination with saidbolts, and a plate through which bolts 0 0 pass, substantially asdescribed.

In testimony whereof I afiix my signature, in presence of two witnesses,this 31st day of May, 1890.
